2005 Saab 9-5 2.2L Diesel · OY05 DWG

The 2005 SAAB 9-5 presents a mixed maintenance picture. The most recent MOT, conducted on 7 May 2022 at 206,567 miles, passed, but the advisory list reveals a vehicle with widespread age-related deterioration rather than acute mechanical failure. The trend is one of gradual, accumulating wear. Corrosion is the dominant theme, appearing consistently across rear suspension arms, coil springs, shock absorbers, and the rear exhaust section. A persistent oil leak and corroded brake pipe were also noted. While none of these individual items were severe enough to cause a failure in 2022, their simultaneous presence suggests a long-term pattern of surface corrosion management rather than proactive component replacement. The vehicle has not been tested since May 2022, meaning its current roadworthiness is unverified for over four years. The mileage record tells a story of very low recent use. The car covered 8,834 miles between the May 2019 test at 178,669 miles and the May 2020 test at 189,039 miles. However, in the subsequent two years leading to the May 2022 test, it covered just 17,834 miles. Crucially, the recorded mileage has remained static at 206,567 miles since that May 2022 pass. This indicates the vehicle has likely been stationary or driven very minimally for the past four years. Such prolonged standing is often more damaging to a car of this age than regular use, as it leads to seized brakes, perished rubber bushes, dried-out seals, and localised corrosion on brake discs and suspension components. A buyer must approach this SAAB with a thorough mechanical inspection focused on its known weak points. The rear suspension requires close scrutiny. The 2022 test flagged corroded nearside and offside lower suspension arms, a corroded nearside rear coil spring, and a worn rear suspension bush. These components will have deteriorated further if the car has been sitting. The rear shock absorbers, noted as corroded with a light oil misting on the nearside unit in 2022, are likely past their serviceable life. The braking system demands equal attention. The 2022 test identified worn and pitted rear brake discs and a corroded offside rear brake pipe. After years of standing, the discs will almost certainly be heavily corroded and the calipers at risk of binding. The persistent oil leak, noted as non-excessive in both 2021 and 2022, needs identification, as a stationary engine can cause seal shrinkage that worsens leaks upon restarting. Beyond the flagged items, a pre-purchase inspection must assess the structural integrity of the subframes and suspension mounting points, as the corrosion noted on arms and springs often extends to these critical areas on older 9-5 models. The handbrake, noted as near the end of its travel in 2021, and the corroded rear exhaust section are further indicators of deferred attention. The static mileage since 2022 is the single most significant concern. A compression test and a careful check for bore wash or coolant contamination are essential before any attempt to start a 21-year-old petrol engine that may have stood for years.
